This area is threatened by factors such as logging, agricultural expansion, and illicit crops, among others, which lead to deforestation and the consequent loss of connectivity. The purpose of this study was to analyze the fragmentation of vegetation cover in the Paramillo National Natural Park (PNN Paramillo), to identify corridors that promote structural connectivity. Using Landsat 8-9 images from 2015, 2018, and 2024, the cover classification and subsequent calculation of landscape metrics were carried out, allowing the identification of potential structural connectivity routes based on least-cost analyses. The results obtained identified the so-called dense forest cover as the dominant one (over 49% of the area), but with an increase in the number of isolated fragments from the edges to the center of the park. The shrublands presented a loss of cohesion associated with anthropogenic pressures, while the intervened areas showed a reduction in their extension with an increase in their internal connectivity, confirming the impact of human intervention. Finally, connectivity modeling led to the delineation of corridors connecting large fragments of dense forest to low-resistance covers, which offers viable solutions to restore structural connectivity.
